### COLLECTION 1 - Spot the Error(s): Perpendicular Bisector Q3 - Groups 2 & 7

As a group, watch the clip and try to spot as many errors as possible.

1. there is a gap between the 2 semicircles that he drew, so when he split the line, the 2 halves of the line were not equal because he didn't split the line equally.

2. This comment has been removed by the author.

3. Group 2:
It is not a perpendicular bisector as the circles/semicircles do not intersect each other at all and there is a gap between them.

4. G2 The circles didn't intersect

5. Group 2
This is not a perpendicular bisector because the circles did not intersect each other.

6. Group 2:
It is not a perpendicular bisector as the circles/semicircles do not intersect each other at all and there is a gap between them.

7. G2 The circles didn't intersect

8. Group 7:
The line was not perpendicular.
There was a gap between the circles.
Although the perpendicular line is a bisector, it does not divide line AB equally.
